hanger rails hereinafter described in detail.

The form of hanger shown in Figs. 1-6, comprises a centrally disposed, relatively flat body portion l'i, provided with diagonally outwardly and thence inwardly converging, depending arms l8, having similarly converging, preferably trans-" versely enlarged rails I!) havin substantially planular brick supporting surfaces 20, said rails of modified form of hanger (Fig. 7). Each of these hangers comprises an arm 35 secured at one end by a bolt 31 to said plate, while its opposite end merges integrally into a transversely elongated body portion 38, the opposite ends of which are deflected downwardly to provide divergent arms 39, terminating in downwardly converging transversely widened rails 40, the upper surfaces of which engage and support the upper surface of each pair of angularly related surfaces ll of V-shaped cutouts 42 in the oppositely directedfaces of each pair of said nose brick 32, so as to thereby provide independent, selfcontained, two brick units, as illustrated.

being integrally connected to said body portion through the respective arms. From the opposite side of said body portioniextend a pair of undercut, recessed, or hooked, arms 2! and 22 of different lengths, and so shaped and related'as to provide for the reception of the flanges 23 and 24 of an angle bar Ebetween them. The shorter arm 21 is of L-shaped form and provides a recess 25 for the flange 23, while it terminates abruptly at 26 above said flange.

.By contrast, the longer arm 22 comprises an inverted J-shaped extension and provides a rece'ss 27 for reception of the angle flange 24, while it terminates abruptly in a depending hooked portion 28. By reference to Fig. 6,it will be'seen that the distance between the extension terminals 26 and 28 and the depth of the respective recesses 25 and 21 is such that the hanger as a unit may be attached to the angle bar 2 transversely of the longitudinal axis of the latter. This is done by first tilting the hanger into the dot-and-dash position 29, shown in Fig. 6, then into the position 38 indicated by dashes, after which it is permitted to drop into the full line position shown. In said last mentioned position the hanger is ready to receive either single. slotted or double slotted brick such as the types shown in Fig. 1. The inner or bar engaging surfaces of saidarms are provided with diagonally extending shoulders or the like 26' and 2 for normally limiting the movement of the hanger transversely of the longitudinal axis of said bar.

In all forms of the hanger herein described, it should be noted that the essential characteristic of the brick supporting rails is that they have angularly related brick supporting surfaces, rather than that the entire cross sections of said rails shall conform to any definite shape or design, and that the term angularly related includes downwardlydivergent as well as convergent brick supporting surfaces, the convergingly surfaced rails being preferred, as they tend to draw pairs of opposed bricks together, rather than to separate them, and thereby operatively supporting pairs of opposed bricks as a self-contained unit.

Referring to Fig. 2, an arch or roof of suspended straight brick 3| is shown, as merging into a vertically arcuate radial nose construction, composed of radially positioned 9 inch wedge brick 32, above and forming a substantially vertical continuation of which is a wall of any desired size of straight brick 33, preferably supported in-- dependently of said nose construction, in accordance with accepted practice. For supporting said nose, there is provided a sectorial section plate 34, rigidly secured in any suitable manner to the under portion of an I-beam 35. To the curved marginal portion of said plate are bolted a-series In the appended claims, the term roof is used to denote the usual upright structures commonly designated as walls, and also all manner of flat,

sloping, and variously curved arches, roofs and the like, to which the invention may be applicable, either in one or more of the identical forms shown or in such modifications thereof as may fall within the scope of said claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is:

1. The combination of a supporting framework,

angle bars carried thereby and comprising angu-' larly related flanges having free edge portions,

and brick-supporting hangers comprising a body i 2. The combination of a, supporting framework, 2

angle bars carried thereby and comprising angularly related flanges having free edgeportions, and brick-supporting hangers comprising a body a portion adapted to lie relatively closely parallel with one of said flanges, and spaced substantially parallel arms of unequal length having hooked ends that surround the angularly directed free edge portions of said flanges, the hookedend of said parallel arm being undercut or recessed sufficiently to permit reception of the free edge portion of the parallel flange, after which by a substantially rotary movement transverse to the axis of said bar the hooked end of the other hanger arm is made to receive and surround the free edge portion of the other flange.

3. The combination of a. refractory roof extending substantially in a plane, a supporting framework comprising an angle bar having its two angularly related flanges respectively substantially parallel with and perpendicular to the plane of said roof, and a brick-supporting hanger having a pair of spaced substantially parallel arms of unequal length having hooked ends that surround the free edge portions of the respective flanges of said bar. I

4. The combination of a refractory roof extending substantially in a plane, a supporting framework comprising an angle bar having its two angularly related flanges respectively substantially parallel with and perpendicular to the plane of said roof, said perpendicular flange extending from said first flange away from the plane of said roof, and a brick-supporting hanger having a pair of a spaced substantially parallel arms, one of which has an angular projection,

extending around the free edge portion of said parallel flange upon that side of said flange opposite to the supported brick, and the other arm being longer than saidfirst arm and extending substantially perpendicular to the plane of said roof and having a hooked terminal portion that surrounds the free edge portion of said perpendicular flange.

5. The combination of a refractory roof extending substantially in a plane, a supporting framework comprising an angle bar having its two angulalfl related flanges respectively substantially parallel with and perpendicular to the plane of said roof, said perpendicular flange extending from said first flange away from the plane of said roof, and a'brick-supporting hanger having a pair of spaced substantially parallel arms, one of which has anangular projection extending around the free edge portion of said parallel flange upon that side ofsaid flange opposite to the supported brick, and the other arm being longer than said first arm and extending substantially perpendicularly to the plane of said roof and having a hooked terminal portion that surrounds the free edge portion of said perpendicular flange, the interior angle of said first arm being of suflicient depth to permit said hanger to be attached to said bar by a'rotary motion transverse to its longitudinal,

axis.

6. A refractory roof, comprising an angle bar, one flange of which extends substantially parallel with the general plane of said roof while the other flange extends angularly away from said plane, and a loosely supported brick-carrying hanger having a generally planular body portion substantially parallel with said first flange and a pair ofrsubstantially parallel arms of unequal length, thefree end of the shorter arm being angular and extending around the free edge portion of said first flange, and the longer arm extending angularly away from the plane of said body portion and having a hooked free end portion that surrounds the oppositely directed free edge portion of said second flange.

7. A refractory roof, comprising an angle bar, one flange of which extends substantially parallel with the general plane of said roof while the other flange extends angularly away from said plane, and a loosely supported brick-carrying hanger having a generally planular body portion substantially parallel with said first flange and a pair of substantially parallel arms of unequal length, the free end of the shorter arm being angular and extending around the free edge portion of said first flange, and the longer arm extending angularly away from the plane of said body portion and having a hooked free end portion that surrounds the oppositely directed free edge portion of said second flange, and the surfaces of the flange-engaging portions of said arms being pro-- vided with angularly directed sections to limit the transverse movement of said hanger upon said bar when supporting brick.
